The construction of the barracks was begun after the
remilitarization of the Rhineland (1936) in 1937/38 in the course of the
German re-armament in the demilitarized zone established by the peace
treaty of Versailles for the security of France and named after
Hugo von Kathen, the last military governor of the
fortress of Mainz. Responsible was the Wehrkreisverwaltung XII in Wiesbaden, which ran the process together with
Robert Barth, the National Socialist mayor of Mainz. The 29-hectare site belonged partially to the
Mombach district and partly to the Gonsenheim district. Mombach had already been incorporated to Mainz in 1907, and in 1937 the then independent community of Gonsenheim was faced with the choice of either paying the development costs for the garrison's new barracks or being incorporated. "Gonsenheim new developments, close to the city limits and thus far from the town centre, would have to be supplied with electricity, gas and water from Mainz." On April 1, 1938, the city of Mainz incorporated the site by enforcement. The completed barracks were occupied by the Field Artillery Regiment 72. A commemorative plaque on the officer's building commemorates the foot artillery regiment "General-Feldzeugmeister" (Brandenburg's) No. 3. In the course of the
bombing of Mainz in World War II, the area was bombed several times during the following war. On March 22, 1945 the war was over for Mainz, American troops had the city under control. With the city commander Louis Théodore Kleinmann, the French occupying power took over the city on July 9. In the same month, the Reichsbauamt Mainz was commissioned by the French administration to repair the Kathen barracks. After the repair, the French military authorities took over the barracks and named it after General
Charles Mangin, who after the First World War was commander-in-chief of the French occupying army on the Rhine based in Mainz. Even today, the lettering "Caserne Mangin" on the main gate reminds us of the name. Gottfried Lenzen, the director of the military construction office in Mainz, was entrusted with the execution of the construction tasks for the occupying troops. In 1949, US armed forces took over the Kathen barracks, which was subsequently given the name "Lee Barracks". American soldiers, their families and their housing estates, NCO Club,
ballpark, Bowling Alley and the Panzerwerk on the border to Mombach shaped the Gonsenheim townscape for the next decades. The
Mainz Sand Dunes were again used for military exercises. With the fall of communism in the cause of the
Peaceful Revolution in the GDR in 1989, the need for large units of mechanized forces in Germany no longer existed. The
8th US Infantry Division was needed during
Operation Desert Shield / Desert Storm and large parts, including the Ready First Combat Team, were deployed in the Middle East. The 8th US Infantry Division was inactivated at a solemn ceremony in
Bad Kreuznach on 17 January 1992, and the American contingent withdrew from Mainz. The area became a conversion area. == Present ==
